u THOMAS H. BROOKS, OF CLEVELAND, OHIO.

INDIRECT RADIATOR.

SPECIFICATION forming part of Letters Patent No. 237,429, dated February 8, 1881.

Application filed March 9, 1880. (Model.)

To all whom 'it may concern Be it known that I, THOMAS H. BROOKS, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvementin Indirect Radiators andIdo here-v by declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to certain improvements in so-called indirect-acting radiators7 for steam-heating purposes, and has for its object such construction of cast-iron devices of this description as will create better circulation of air, more heating or radiating surface, and consequent economy in fuel, or a proportionate increase in heat from a given quantity. The circulation of the steam through the various sections of the apparatus isv also effected in the most thorough manner by a rib cast into each section, and so arranged that a perfect movement of the steam from the inlet to the i outlet is secured and all its heating power utilized to the best purpose.

In the drawings, Figure l is a view of my improved indirect-acting radiator, one section onlyT ofthe nest or series being shown, in which A A are ribs or projections formed upon the side surfaces of the steam-chamber in wavelike shape and in alternate order, and extending beyond the upper and lower edges thereof, as shown, so as to present the utmost radiatin g-surface. The curved or wave-like construction of theseribs is designed to cause a free circulation of the air and bring it as much as possible in contact with the heating-surface of the radiator as it passes upward to the register or opening admitting it to inclosure to be warmed. B is an inner rib, supported at B', and dividing the inner chamber of each section into two equal portions below the rib, and forming a channel above, as shown by dotted lines B B in Fig. l, through which the steam passes from the port C around the rib in the direction indicated by the arrow, and out at the port C', upon the opposite side, into the next section of the radiator. The curved ribs are so arranged that each one upon the left side of a section ts between two ribs upon the right side of the next section, and so on throughout the series, of which any desired number may be arranged.

Fig. 2 is a vertical section on the line x in Fig. l, showing the end of the rib B dividing the interior horizontally and centrally, as explained.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The radiator formed in two or more sections,-

as described, and having each section provided with a horizontally-central dividingrib, B, with its central support, B/and the inlet and exit steam -ports C C', arranged respectively on each side ofsuch central support, substantially as set forth and shown.

This specification signed and witnessed this 19th day of December, 1879.
